Regarding the oscillator circuit which is comprised of the 6A7's cathode, control grid, and screen grid. These elements are configured as a triode, so more or less the cathode should be @ 0v, control grid a small amount - voltage like -3 or -4v, and the screen grid a high + potential like +80v. If the control grid is reading a + voltage the oscillator is not running. The voltage must be measured w/ a high input impedance meter so the meter won't load the circuit. 

#s 13 and 14 have to be in the circuit to resonate the SW section of the osc coil. If I counted my 0s right it's a .002250mmfd or pf. If you had a .0022 ceramic disc cap you could chuck that in so #8 can tune 6-18mc.

#17 and 18 are the grid leak resistors for the osc. 17 is for the BC/POL band and 18 for the SW band. They too need to be in the circuit. As for the POL band I need to do a little research cause it looks like voodoo...
